Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521246, here are decompositions:

3 + 521243 = 521246
67 + 521179 = 521246
73 + 521173 = 521246
79 + 521167 = 521246
109 + 521137 = 521246
127 + 521119 = 521246
139 + 521107 = 521246
199 + 521047 = 521246

Showing the first eight; more decompositions exist.
